Rattle & Roar features re-imagined versions of tracks originally performed by bluegrass legends Lester Flatt and Earl Scruggs, just as the Earls did with their 2014 self-titled debut record. Among Rattle & Roar's 17 tracks are "Steel Guitar Blues," "You Can Feel It in Your Soul," "The Train That Carried My Girl From Town" and "All I Want Is You." A complete track listing is below.

"I hope people who don't know Flatt & Scruggs hear this and think it's totally new music," Douglas says in a press release. "Then, I hope they find out what we're doing and go out and buy every Flatt & Scruggs record they can find."
